• Tap
• Tap and hold
• Drag
• Swipe
• Double tap

Session 4: Parts of a Computer and peripherals

A computer system is a programmable device made to store and retrieve data as well as carry out logical and mathematical operations to generate useful output. The input unit, central processing unit (CPU), and output unit are its three primary components.

• Keyboard – Keyboard is the input unit.
• Central Processing Unit – CPU is the processing unit.
• Monitor – Monitor is the output unit.

Central Processing Unit

The Central Processing Unit (CPU) is also known as brain of computer, CPU process all the mathematical and logical problems received from the input device and gives the output to the monitor just like a human brain.

There are 3 main parts of the CPU –

• Control unit – It controls different parts of computer.
• Processing unit – Performs all the mathematical and logical operation.
• Memory unit – It work as a storage room, where data is stored temporarily in RAM as well as for a long time (ROM).
  

Understanding RAM and ROM

RAM stands for Random Access Memory; it is also known as volatile memory. RAM is used to store the data that is currently open in the computer. ROM stands for read-only memory, which stores the data and instruction permanently. 

Difference between RAM and ROM –

RAM	ROM
Temporarily stores information	Permanently stores information
Information is lost when computer is switched off	Information is stored when computer is off
Information can be changed easily.	Information can be changed easily.
It is also known as volatile memory	It is also known as non-volatile memory

Motherboard

The motherboard, is also known as the system board, is a main circuit board inside the computer, it connects input, processing, and output devices.

Storage devices

Storage device is used to store the files and folders or digital information which you can carry easily from one place to another place using USB flash drive, hard disk, CD, DVD drives etc.

Computer can measure the amount of data stored on a digital device using bits and bytes. The Bit is a smallest storage unit (Bit represented by 0 or 1). Eight bits combined together and create one byte.

• 8 bits make a 1 byte
• 1024 bytes make a 1 kilobyte (KB)
• 1024 KB make 1 megabyte (MB)
• 1024 megabyte make 1 gigabyte (GB)
• 1024 gigabyte make 1 terabyte (TB)

Ports and connections

Ports are the slots or channels where we insert the cables for the external hard drive, mouse, and keyboard. Ports helps us to connect input, output, and storage devices within a computer system. There are several types of ports that you can use to connect an external device.

• USB Port – USB stands for Universal serial bus, USB helps to connects peripheral devices, such as a mouse or a keyboard or a printer to a computer.
• Display port – It helps to connect monitor, or any display unit to the computer. There are two types of display port Video Graphics Array (VGA) and High-Definition Multimedia Interface (HDMI) depending on the requirement.
• Audio ports – It help to connect microphone, speakers, and headphones to a computer system.
• Ethernet port – Ethernet port is used for connecting the system to high-speed Internet cable.
• Power port – Power port is used for connecting the computer system to the power supply.

Session 5: Basic Computer Operations

A computer system consists of two main parts—the hardware and the software.

• Hardware – The physical parts that we can see, and touch are called the hardware. Example, Keyboard, monitor, CPU etc.
• Software – The software that we cannot see makes the hardware work the way we want. for example, Operating System, LibreOffice Writer etc.

Basic functions performed when a computer starts

When we switch on a computer, computer automatically runs a basic program called BIOS (Basic Input/Output System). The BIOS first run a self-test. If the self-test shows that the system is fine, the BIOS will load the Operating System.

Using the keyboard

A keyboard helps to insert text, number and command into the computer. There are various types of keys are available on keyboard –

• Function keys – Function keys start from F1 to F12 to perform specific work. for example, F1 key is used to open help program in computer.
• Control keys – Control keys perform special functions depend on the purpose. for example, Control (CTRL), Shift, Spacebar and ALT.
• Enter key – Enter and Return keys helps to move the cursor to the beginning of a line.
• Punctuation keys – Colon (:), semicolon (;), single quotation marks (‘ ‘), double quotation marks (” “) and question marks (?) are known as punctuation keys.
• Navigation keys – The arrow keys, END, HOME, Page Up and Page Down are known as navigation keys.
• Command keys – Insert (INS), Delete (DEL) and Backspace are known as command keys.
• Windows key – Pressing this key opens the Start menu.

Using a mouse

A mouse is a small device that you can use to move, select, and open items on your computer screen.

• Roll over/hover – Moving a mouse over a file or folder in file explorer, it will show the details of file and folder.
• Point and click – The mouse allows you to select an item on the screen.
• Drag and drop – move the item to a new location.
• Double-click – When we double-click the file icon, it will open the file.

Session 6: Performing Basic File Operations

What is files and folders in computer system?

All the information in computer stored in files, every file name has a file name and extension that identifies the file type. The file name and file extension are separated by a period or a ‘dot’. for example, notepad file has an extension ‘.txt’, image file has an extension ‘.jpg’, sound file has an extension ‘.mp3’. Folder is a collection of files and sub folder.

Session 7: Communication and Networking – Basics of Internet

What is Internet?

The Internet is a global network of interlinked computers and electronics devices. It is a vast network system that links computers worldwide. Every piece of information on the internet is kept in a webpage on the internet.

Uses of the Internet

There is no limit to what you can do online, but some of the most common uses of internet are –

• Searching Information
• Online Shopping
• Online Banking
• Online learning
• Entertainment

• An Internet Service Provider (ISP) – the telephone company which provides the Internet connectivity.

Types of connections

There are two ways for connecting your computer to the internet:

• Wired connections – When computer is connected to the intenet using wire (Fibre optical, Ethernet cable or Co-axial cable) is called wired connection.
• Wireless connection – When the computer is connected without wire (Wi-Fi, Cellular, Satellite communication etc.) is called wireless connection.

What is Bandwidth?

Bandwidth is the maximum amount of data that can be transmitted over a network in a certain amount of time. The bandwidth commonly measured in bits per second or bytes per second. for example, If bandwidth having a capicity of 100 MBPS, it means that network cannot transfer the data more than 100 MBPS.

The data transfer speed can be calculated in terms of bits per second, for example,

• 1 Kbps (kilo bits per second) = 1000 bits per second
• 1 Mbps (mega bits per second) = 1000 kilo bits per second
• 1 Gbps (giga bits per second) = 1,000 mega bits per second

Session 8: Communication and Networking – Internet Browsing

What is World Wide Web?

World wide web is a hypertext based information, files, images and videos stored in a web pages and accessible through the internet. This hypertext helps you to navigate between the web pages.
